## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agosint-domain-intelligence-84d6c978 -d '<json body>'
```

Example prompt: Can you check whether the domain 'secure-banklogin-verify.com' is legitimate — I want to know how old it is, who registered it, what DNS records it has, and whether it has proper SPF and DMARC email security set up?

## When to prefer this

Choose this endpoint when you need a comprehensive, single-call domain intelligence snapshot combining WHOIS/RDAP registration data, full DNS records, email security posture (SPF, DMARC, MTA-STS), DNSSEC, TLS certificate status, and hosting network identity. Prefer it over standalone WHOIS or DNS tools when assessing phishing risk, vetting an email sender, or auditing a domain's mail infrastructure all at once. It is especially useful when you need to correlate registration age with email security gaps to identify suspicious or newly registered domains.

## Known failure modes

- Domain not found or never registered — returns empty or null RDAP/WHOIS data
- RDAP/WHOIS rate limiting by registrar — partial or missing registration data
- DNS resolution failure — DNS records unavailable or timeout
- Private/redacted WHOIS — registrar and registrant info withheld under privacy protection
- TLS certificate absent — domain has no HTTPS, certificate fields will be null
- Company identification unavailable — hosting network returned but company name not resolvable
- Invalid domain format — request rejected if input exceeds 253 chars or is malformed

## How this service works

Domain intelligence and phishing-risk signals: domain age and expiry (RDAP/WHOIS), registrar, DNS (A, AAAA, MX, NS, TXT, CAA), SPF, DMARC and MTA-STS, DNSSEC, TLS certificate issuer and expiry, hosting network, and the company behind the site when it can be identified. Use when: deciding whether a domain, link or email sender is legitimate, or checking a domain's mail setup.

## Output

A structured JSON object containing: domain registration date and expiry, registrar name, full DNS record set (A, AAAA, MX, NS, TXT, CAA), SPF and DMARC policy details, MTA-STS policy, DNSSEC validation status, TLS certificate issuer and expiry, hosting ASN and network name, and identified company behind the domain where available.
